Monterrey, Mexico (MTY): At the airport again

I am at the airport in the Aeromexico Salon;

The check-in process was smooth and no issues. The airport is cold though. I had no issues through security which was a breeze. This is really a nice airport.

I was taking pictures and was told to stop by the security officer so I did. I was watching an Aviacsa Boeing 737-300push back as well as an Interjet A320 pulling in.

I then left and walked around and found a few lounges; Aeromexico's and and Mexicana. I gained access to the Aeromexico Salon with my boarding pass and my Presidents Club card. I also could have gained access using my American Express Gold, Black or Platinum card to the American Express Centurion Club.

I await the flight...
